Chromans 3 and o-isopentenylphenols 4 are synthesized in satisfactory to good yields and selectivities by the reaction of phenols and isoprene in the presence of the commercially available acid faujasite zeolite HSZ-360.

Montmorillonite clays catalyze the rearrangement of substituted allyl phenyl ethers to provide ortho-allyl phenols, chromans and coumarans under mild conditions.
REGIOSPECIFIC ALKENYLATION OF PHENOLS BY ISOPRENE PROMOTED BY Pt(II) AND Pd(II) COMPLEXES

Catalytic alkenylation of phenols with isoprene is promoted by Pd(II) or Pt(II) complexes.Ortho-isopentenylphenols are obtained together with the corresponding 2,2-dimethylchromans.The catalytic activity of the two d8 ions is compared.A possible mechanism is discussed.
REGIOSPECIFIC ALKENYLATION OF PHENOLS BY 1,1-DIMETHYLALLENE PROMOTED BY PLATINUM CATALYSTS
Renzi, Augusto De,Panunzi, Achille,Saporito, Antonio,Vitagliano, Aldo
, p. 993 - 996 (2007/10/02)
1,1-Dimethylallene reacts with phenolic substrates in the presence of catalytic amounts of platinum(II) complexes.A regiospecific C-alkenylation takes place, affording o-isopentenylphenols and 2,2-dimethylchromans.Possible reaction mechanisms are also discussed.
